Web-based vector grids

[Razzerman II]

Hello All,

First time post - hoping for some insightful advice.

I want to create a web-based solution for drawing user defined vector based grids (nets). Basically, the user enters the size of each rectangle and the resulting svg is exported so that it can be opened in Illustrator.

I've been doing some research, and I get the impression that there is no one tool that can accomplish this. A combination of html, svg and javascript seems to be one solution.

I've got limited experience programming wise, and was wondering how someone who has experience would accomplish this relatively simple task.

Thanks for any input.

Cheers,

Ray
